Step-by-Step Guide to Automate Inventory with Amazon MWS API

Obtaining Access Keys and Tokens

To access the MWS API, you’ll need your Access Key ID, Secret Key, Seller ID, and Marketplace ID. These can be found in your Seller Central account under “Settings” -> “User Permissions.” Make sure to keep these keys secure as they provide access to sensitive information.
